3rd-century Roman consuls

Diocletian ( ; ; ; 242/245 – 311/312), nicknamed Jovius, was Roman emperor from 284 until his abdication in 305. He was born Diocles to a family of low status in the Roman province of Dalmatia. As with other Illyrian soldiers of the period, Diocles rose through the ranks of the military early in his career, serving under Aurelian and Probus, and eventually becoming a cavalry commander for the army of Emperor Carus. After the deaths of Carus and his son Numerian on a campaign in Persia, Diocles was proclaimed emperor by the troops, taking the name "Diocletianus". The title was also claimed by C

Roman emperor from 193 to 211

Marcus Aurelius Antoninus (born Lucius Septimius Bassianus, 4 April 188 – 8 April 217), better known by his nickname Caracalla (; ), was Roman emperor from 198 to 217 AD, first serving as nominal co-emperor under his father and then ruling alone after 211 AD. He was a member of the Severan dynasty, the elder son of Emperor Septimius Severus and Empress Julia Domna. Severus proclaimed Caracalla co-ruler in 198, doing the same with his other son Geta in 209. The two brothers briefly shared power after their father's death in 211, but Caracalla soon had Geta murdered by the Praetorian Guard

Aurelian (; ; 9 September ) was a Roman emperor from 270 to 275 during the Crisis of the Third Century.

For his success in restoring the Empire's territorial integrity, Aurelian was honored with the title ("Restorer of the World").

Marcus Aurelius Antoninus (born Sextus Varius Avitus Bassianus, 204 – 13 March 222), better known by his posthumous nicknames Elagabalus ( ) and Heliogabalus ( ), was Roman emperor from 218 to 222, while he was still a teenager. His short reign was notorious for religious controversy and alleged sexual debauchery. A close relative to the Severan dynasty, he came from a prominent Syrian Arab family in Emesa (Homs), Syria, where he served as the head priest of the sun god Elagabal from a young age. After the death of his cousin, the emperor Caracalla, Elagabalus was raised to the Principate at 1

Roman Emperor (208-235)

Before becoming emperor, Macrinus served under Emperor Caracalla as a praetorian prefect and dealt with Rome's civil affairs. He later conspired against Caracalla and

He shared the latter title with his co-emperor and superior, Diocletian, whose political brain complemented Maximian's military brawn. Maximian established his residence at Trier but spent most of his time on campaign. In late 285, he suppressed rebels in Gaul known as the Bagaudae. From 285 to 288, he fought against Germanic tribes along the Rhine frontier. Together with Diocletian, he launched a scorched earth campaign deep into Alamannic territory in 288, refo
